The PlanetQuest Observing Cards are designed to give telescope operators and other interpreters a new way of explaining the night sky. Relating common observing objects to our search for exoplanets makes these spectacular sights more understandable....(View More) These cards are a great resource for use at observing night events, providing new stories to tell about commonly viewed celestial objects.(View Less)

In this activity, students are reminded that the Universe is made up of elements and that the heavier elements are created inside of a star. They are then introduced to the life cycle of a star and how a star's mass affects its process of fusion and...(View More) eventual death. Students discuss the physical concept of equilibrium as a balancing of forces and observe an experiment to demonstrate what happens to a soda can when the interior and exterior forces are not in equilibrium. An analogy is made between this experiment and core collapse in stars, to show the importance of maintaining equilibrium in stars. Finally, students participate in an activity which demonstrates how mass is ejected from a collapsed star in a supernova explosion, thereby dispersing heavier elements throughout the Universe. This activity is part of a series that has been designed specifically for use with Girl Scouts, but the activities can be used in other settings. Most of the materials are inexpensive or easily found. It is recommended that a leader with astronomy knowledge lead the activities, or at least be available to answer questions, whenever possible.(View Less)

In this lesson, students will be introduced to how the Doppler effect changes our perception of wavelengths of sound (pitch) and light (color). Students will model how astronomers use the line spectra of stars to identify elements in the stars and...(View More) the speeds of galaxies in the universe. Requires some special equipment for spectral analysis and a darkened room for viewing spectra. Suggestions are included for introducing the Doppler Effect for students unfamiliar with this concept. This activity is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1929 Cosmic Times Poster.(View Less)

In this lesson, students will investigate the Doppler Effect and discover how the same principle can be used to identify a possible tornado in storm clouds and investigate the rotation of distant galaxies. Students should be familiar with the...(View More) electromagnetic spectrum and the concept of Doppler Shift (links to background information are provided). Materials required for every group of 2-4 students include: a Slinky toy, safety glasses, meter stick, and colored pencils. This lesson is part of the Cosmic Times teachers guide and is intended to be used in conjunction with the 1965 Cosmic Times Poster.(View Less)

This activity includes twelve monthly star charts to identify the stars that are visible in the night sky and that are known to have planets around them. The star maps can be used to find constellations and identify stars with extrasolar planets....(View More) (Northern Hemisphere only, naked eye)(View Less)

In this activity, students experience a demonstration of light scattering that explains the blue colors in the Intersetllar Medium (ISM) nebulae, and the reddening of stars viewed through the ISM. It also explains the blue appearance of the sky on...(View More) Earth and the reddish appearance of the Sun during sunsets. The demonstration is best done before or during a lesson on the ISM when light scattering is discussed. This activity is one of two supporting the scientific investigation of the ISM, and is linked to reading material, reading review questions and problems, a teacher answer sheet, and glossary.(View Less)
